Hidden
A card with [Hidden] can be put face down on the board, to save for later.
- Hide: on your turn, outside a Showdown, pay 1 Power of any Domain and put the card face down at a battlefield you control. One hidden card per battlefield.
- Wait: you can't play it the turn you hide it. From the very next turn on (that's your opponent's), it counts as a [Reaction].
- Play it free: no Energy, no Power. A unit arrives at that battlefield.
- Keep the battlefield. A battlefield with none of your units on it isn't yours any more, and if you stop controlling it, the hidden card goes to your trash.
- A hidden unit arrives at once when you play it, like any unit: it doesn't wait on the Chain.
Hiding isn't playing: nothing goes on the Chain, and your opponent only sees a face-down card.
